Domestic manufacturers generally uses the dorsal end of dense, black foam bottom, back the end of the simple imitation of foreign products, remain unresolved contract issues.
Current: fabric layer + Layer + elastic the same color fabric + foam + fiberglass keel ground fitting five-layer composite technology, product stability later without shrinkage.
Back is white at the end of the back, indicating that raw materials used is a material. Foreign brands and well-known, not superfluous here. In addition to other brands are using single layer of dense foam at the end of the end of such late product stability cannot be guaranteed.
